Ordinateur tres lent suite virus

Bonjour,

voila, il y a quelques jours, dès que j'ouvrais une page internet, des pages about blank s'ouvraient aussi... la misere
bref j'ai telechargé avast et ad-aware comme anti virus et depuis plus de page about blank :)

seulement, depuis mon ordi rame (beaucoup). Il me dit souvent que tel ou tel programme ne repond pas, les fichiers mettent 10 min a s'ouvrir et internet rame pas mal...

j'ai telechargé HijackThis et voila le resultat (si quelqu'un pouvait me dire où se trouve le probleme ce serait super !!!) :
